... except for the "global" scope, for which symtable_exit_scope() is
never called.  But the last reference to *that* scope (st->st_cur) gets
cleaned up in PySymtable_Free().  Correct?

So the two things I thought were glitches are actually cancelling each
other out.  Very good.  Thanks for your help.
